I usually use <table>_ID for primary *and* foreign key. Using the same name in the source and target table (when possible and logical) also allows you to use the USING clause in a join, and keeps columns readable even if you alias the table to something short. However naming conventions are a matter of opinion. In general within a team or company decide on one naming convention and stick to it (within reason). Mark -- Mark Rotteveel
